The purpose of this study was to assess the accuracy of a landmark technique for cannulation of the greater saphenous vein (GSV) near the medial malleolus. We performed bedside ultrasound in a convenience sample of 100 children, ages 3 to 16 years, to evaluate the anatomy of the GSV at the ankle. Despite the proposed constancy of the landmark technique regardless of patient age, the GSV location varied significantly with increasing patient age and weight. In children less than 10 years old or weighing less than 40 kg, the traditional landmark rarely predicted the precise location of the GSV.
本研究旨在评估一种在内踝附近进行大隐静脉（GSV）插管的地标技术的准确性。我们对 100 名年龄在 3 至 16 岁的儿童进行了床边超声检查，以评估踝部 GSV 的解剖结构。尽管地标技术的位置通常是固定的，与患者的年龄无关，但 GSV 的位置随着患者年龄和体重的增加而有显著变化。在年龄小于 10 岁或体重小于 40 公斤的儿童中，传统地标很少能准确预测 GSV 的位置。
